我買了一台1985年的300D 柴油車(渦輪增壓) 從加州開了1200英哩到華盛頓.
剛開始很順暢.但旅程一半時.上坡車輛開始力不從心.
我帶著她去給賓士技師做微調的工作.更換了加州式樣的空氣濾清器.也替換了汽門室墊片和調整汽門間隙.在這樣的真實檢測下花了美金600元.
當我帶走她. 還是很沒力.
她似乎花了永恆的時間以達到第二檔.
然後也花了更永恆的時間以達到第三檔.
但是第四檔的表現才比較正常.
引擎轉速在約3500 rpm時才換檔.
我已經去過很多賓士車相關的網站以尋求這樣的問題是出在哪裡!
我先生已經不太高興了!
有人有任何想法或建議嗎??
I bought my 1985 300D turbo in California and drove it to Washington State.(1200 mi) It did fine but was losing power on hills about half way through the trip. I took it to the Mercedes mechanic who did a tune up, replaced the California style air filter, replaced head gasket and adjusted the valves. Yes, it was a $600. reality check. When I picked it up, it had no power....it took forever to shift to 2nd gear, then forever to shift to 3rd, did fine in 4th gear. The tach was up to approx 3500 rpm when shifting into gears. I have gone to many Mercedes web sites trying to find out what the problem is. My husband is less than happy (and he is a Mopar man) Any ideas?
你好。
您的技師可能敲鬆了某處的真空管.
這狀況蠻常見.當在頂部與汽門蓋附近施工時.
看看汽門蓋背部有沒有任何真空管線鬆脫或破損.
這些真空管線是由硬質塑膠製成的而且以顏色加以識別.
也記的檢查從進氣岐管背部出來的超壓管線(overboost)到分油泵浦上的ALDA.
這不是一個壞想法去清洗班卓琵琶(banjo)螺栓(一個在進氣岐管和一個在分油泵浦上的alda)
看這些線是不是被煤灰或油泥所阻礙起來.
您應該看看進氣岐管背面的螺栓.
只要循著防火牆側的那管線到分油泵浦上的ALDA
由於美規車輛所增加關於環保溢散的設備.
這引擎室會由於真空管的增加而有些許不同.
Hello.
Most likely your mechanic has knocked loose a
vacuum line somewhere. Not uncommon when
working around the head and valve cover.
Just look in the back of the valve cover and
look to see if any of the vacuum lines are
disconnected or broken.
These lines are hard plastic and different
colors.
Also check the overboost line going from the
back of the intake manifold to the alda.
It is not a bad idea to clean the banjo bolts(
one at manifold and one at alda).
and the lines since they can clogg up with
soot and oil.
You should see the bolt on the back of the manifold
just follow it to where it goes to the firewall then to
the alda.
This engine bay looks a little different then yours since there are
more vacuum lines for the increased emissions devices.

這是進氣歧管。這螺栓是在靠近防火牆側.而且它有一條硬塑膠材質的管線依附在上面.
This is the intake manifold.
The bolt is on the firewall side it has
a hard plastic line attached to it.

哇!那技師看過您!!
